Cannabis Pollen in Stigma
The pollen from a male cannabis plant is nestled into the female stigma and is in the process of transferring genetic material to the female to create a seed. The pollen is 20 um in diameter. A single grain of pollen is too small to see with the human eye. The pollen is scattered by air current to pollenate the female plant.
